I was once paid a very good compliment.
'What you do isn't Taekwondo'
Most people wouldn't view that as a compliment and it would have probably earned the person saying it some 'firm words'. But the way I interpret patterns is to look at the movements as well as the techniques.
For example, let's look at the lead or reverse front punch and the possible applications;
1) Punch them. Easy.
2) Grab them, return your fist to the hip and punch them. Better than above and still easy.
3) Use the punch to enter in close, punching past their head and rolling your arm so that you steal their balance, take them to the ground. Again, still easy and still the technique from the pattern.
4) Use a palm heel. More socially acceptable (after all you only slapped them) but not the technique. However it's still the movement.
5) Turn the movement into an eye jab. Again, it's the movement that counts, not the technique.
6) Ad infinitum!
I find that if you try to stick with 'just' the pure techniques contained within the pattern, then you're very limited as to how you can make the pattern work for you (something which is also very important).
